Definitions

  • the present invention relates to wireless communication systems. More particularly, the present invention relates to method and apparatus for unidirectional delivery of services.
  • the present invention has the objective of delivering UMTS based services while a mobile station is attached to a wireless local area network (WLAN) system.
  • WLAN wireless local area network
  • the present invention is employed within a wireless communication system characterized by comprising a UMTS receiver that acts as a repeater for UMTS signals and a format converging unit for translating between UMTS formats and WLAN formats.
  • the invention is employed within a network having both a UMTS system and a WLAN system.
  • the system accommodates stand-alone mobile stations having a dual mode capability of selectively operating in UMTS and WLAN environments.
  • a mobile station (UE) operating in the WLAN environment registers with the WLAN system and provides its UMTS identification for tracking UMTS traffic.
  • the WLAN forwards the mobile station identification (ID) to the UMTS receiver unit which is tuned for any activities involving the mobile station (UE).
  • the UMTS receiver forwards any traffic, for example, paging messages, short message service (SMS), multimedia message service (MMS) and so forth, addressed to one of the registered mobile stations in the associated WLAN system serving the registered mobile stations. Traffic is forwarded to a unit that translates the message formats of the received traffic (flows) into WLAN formats which is then forwarded to the WLAN system.
  • the WLAN system then forwards the traffic to the corresponding access point (AP) serving the mobile station.
  • AP access point
  • the UMTS receiver forwards any traffic (e.g., paging messages, short message service (SMS) multimedia message service (MMS) and the like) address to the registered mobile station(s) through the associated WLAN system serving that (those) mobile station(s).
  • traffic e.g., paging messages, short message service (SMS) multimedia message service (MMS) and the like
  • MMS multimedia message service
  • the message is transferred through the converging layer 34 to the access point (AP) 36 servicing the mobile station, see Figure 1 .
  • Figure 1 is a diagram showing a UMTS system with an underlayed WLAN system and which is useful in describing the features and operation of the present invention.
  • Figure 2 is a flow diagram useful in explaining the manner of operation of the present invention.
  • Figure 1 shows an arrangement 10 of a UMTS system 12 with an underlayed WLAN system 14. The arrangement of Figure 1 will be described in conjunction with the technique for delivery of UMTS-based services when a mobile station is served by the WLAN system.
  • User terminal 24 when within the range in the WLAN environment 14 and operating in the WLAN mode 24a, registers with WLAN 20, at step S1.
  • WLAN 20, at step S2 registers, with UMTS repeater 18, the user identification (ID) of terminal 24 for the UMTS service watch, the user ID being transferred to UMTS repeater 18.
  • the UMTS receiver 26 is tuned for any services addressed to registered IDs.
  • UMTS 12 at step S3 transfers such a service, in the example given, a page message, to UMTS repeater 18.
  • the repeater 18, which includes a transmission tower 28 (see Figure 1 ), transmits the page message over a radio channel 30 to the WLAN 20, at step S4.
  • the WLAN format converter 22 converts the UMTS format of the page message into a WLAN message format, at step S5, having received the page message transmitted over the UMTS transmission tower 28 through wireless channel 30 and WLAN receiver antenna 32.
  • Format converter 22 transfers the WLAN message format to WLAN 20 which, through converging layer 34 ( Figure 1 ), directs the message to the appropriate access point(s) 36 to provide UMTS service notification over the WLAN coverage area 14, the broadcast message being transmitted to those registered users operating in the WLAN mode 24a, typically through a transmission antenna, not shown for purposes of simplicity.
  • SMS short message service
  • MMS multimedia message services
  • broadcast unidirectional multicast services
